Title: Memory control circuit
Inventor: KOMAGINE TAKASHI
IPC: G06F12/14
Filed: 1989-12-26
Abstract: PURPOSE:To reduce the size of the memory control circuit by inputting an instruction strobe signal and a data strobe signal of a processor circuit to difference AND circuits, applying the output of an address decoder circuit to other- input sides of the AND gate circuits and ANDing their inputs, and applying their outputs to a memory device through an exclusive OR circuit. CONSTITUTION:When processor circuit 1 attains instruction access, the instruction strobe signal is ANDed by an AND gate circuit 4 with the output of an address decoder circuit 2 and the result is inputted to the select terminal of a memory device circuit 3 through the exclusive OR circuit 6. For data access, the output of an AND gate circuit 5 which ANDs the data strobe signal with the output of the address decoder circuit 2 is inputted to the select terminal of a memory device circuit 3 through the exclusive OR circuit 6. The exclusive OR circuit 6 inhibits simultaneous access from being attained with the instruction data and data strobe signals. Consequently, since the number of memory circuits can be decreased, the size is reducible.

Title: High pressure casting method for casting
Inventor: HARADA MASAYUKI
IPC: B22D17/32
Filed: 1988-12-30
Abstract: PURPOSE:To prevent the development of gas defect, shrinkage hole defect, etc., in a casting by locally pressurizing molten metal in a cavity for the prescribed time when advancing velocity of a plunger tip drops lower than the prescribed setting velocity. CONSTITUTION:The molten metal is poured into a sleeve 6, and the tip 4 in a sleeve 6 is advanced with a driving device, and the molten metal is poured under pressurizing into the cavity 2 through a weir 3 and after filling up, by driving a local pressurizing pin 7, the molten metal is locally pressurized to make the casing. In this operation, by detecting the velocity of the plunger rod 5, the velocity of the plunger tip 4 is detected and the time point of the completion of the filling-up in the cavity 2 can be accurately informed. The time point of this completion of the filling-up is grasped as the time point when the detected velocity drops less than the preset prescribed velocity, and after passing the prescribed time from this time point, the local pressurizing is started and further after passing the prescribed time, the local pressurizing is stopped. By this method, the casting having excellent pressure resistance and strength is produced.

Title: Speed controller of motor for image forming device
Inventor: SAKATA TOMOSHI
IPC: H02P29/00
Filed: 1989-12-26
Abstract: PURPOSE:To effectively control a PLL speed even immediately after a motor is rotated by starting the motor after a rotation command signal of the motor is input, and releasing the start when predetermined number of rotation pulse signals are counted. CONSTITUTION:A speed difference detection circuit 30 obtains the period of an encoder signal EN by using a reference clock signal fs in a counter. A composite circuit 50 receives a pulse width modulation signal PWM from a modulator 40, and outputs a speed control signal SR. The signal SR varies at its ratio of ON/OFF time in response to the signal EN, and controls a current to a motor 100 to control the rotating speed of the motor 100. Thus, the motor 100 reciprocates while being controlled at its speed, and the motor 100 is stopped if a motor rotation/stop command signal CONT becomes low when an optical system reciprocates at a distance response to an original size.

Title: Semiconductor device
Inventor: OKUYAMA TETSURO
IPC: H01L21/822
Filed: 1989-12-25
Abstract: PURPOSE:To protect each circuit from an electrostatic breakdown by a method wherein protective elements which reduce a change in voltages of a power- supply wiring and a ground interconnection of a circuit having a small capacitance are installed between wirings. CONSTITUTION:A plurality of circuits A, B which do not posess at least either power-supply wirings 6, 10 or ground interconnections 8, 12 jointly are formed on the same chip 1. Protective elements 14 to 17 which reduce a change in voltages of the power-supply wiring 6 and the ground wiring 8 of the circuit A having a small electrostatic capacity are installed between the wirings 6, 10, 8, 12. Consequently, when static electricity is applied to the individual circuits A, B, the static electricity flows from the wiring on the side of the circuit having a small electrostatic capacity to the interconnection on the side of the circuit having a large electrostatic capacity via the protective elements 14 to 17; the static electricity is absorbed on the side of the circuit having the large electrostatic capacity. Thereby, it is possible to protect the individual circuits A, B from an electrostatic breakdown.

Abstract: PROBLEM TO BE SOLVED: To avoid excessive discharging of a battery by judging that the residual capacity of the battery is decreased when a detected battery voltage value is lower than a voltage threshold which is set from battery current, or when a detected discharge current estimation value is in excess of a discharge current estimation threshold.

The residual capacity of the battery is calculated from the detected value, and lighting, flashing or turning off of indicating lamps 40 to 42 is controlled from the residual capacity. Indicating level switching is conducted from the first to fifth voltage threshold values which are set from a battery current value flowing from the battery 21 (obtained by experiment for each battery type), and the discharge current estimation threshold.  In this case, it is judged from both the threshold values until the residual capacity of the battery reaches a required charging level, and from only the voltage threshold when it reaches the required charging level.
